Exploring English Language Learners’ Vocabulary Knowledge and Usage When Speaking
International Journal of Applied Linguistics, EarlyView.ABSTRACT Vocabulary forms a fundamental component of speaking ability, as it enables speakers to convey meaning accurately, fluently, and effectively. Although the relationship between vocabulary and speaking has been investigated to some extent, gaps remain in understanding the link between learners’ vocabulary knowledge and their speaking proficiency,

International Journal of Applied Linguistics, EarlyView.ABSTRACT Self‐directed Learning (SDL) is an important skill for learners of all ages and phases of life. Generative AI facilitates self‐directed second language (L2) learning by providing interactive, personalised access to online resources. However, existing research on AI‐assisted self‐directed L2 learning focuses on adult learners in higher ...

Governing for Digital Resilience: Rethinking Inclusion for WSIS+20 and Beyond
Policy &Internet, Volume 18, Issue 4, December 2026.ABSTRACT At the WSIS+20 juncture, this article asks what conditions enable individuals to participate meaningfully in digital life, and how governance arrangements should be assessed accordingly. Multistakeholder governance has distributed authority across actors, but not necessarily the capacity to shape or respond to digital conditions. We argue that

Dianci bileiqi, 2018 复合绝缘子状态评价指标数据变化具有时空特性。复合绝缘子评价指标权重值随时间变化且不同指标数据随时间变化程度不同,具有时间渐变性和时间敏感性的特点,而绝缘子所处空间环境差异影响专家对评价指标主观权重大小认知。依据复合绝缘子所处空间特点确定主观权重,克服复合绝缘子空间特性对权重的影响;以熵权法确定评价指标的客观权重,体现指标数据变化的时间渐变特性;以博弈模型组合主观权重和客观权重,以主观权重值弥补客观权重值无法体现时间敏感性的不足,兼顾复合绝缘子指标权重的时间和空间特性 ...

Shuitu Baochi Xuebao, 2018 为研究花岗岩崩岗土体水分特征曲线及其影响因素，以福建省安溪县崩岗崩壁土为对象，通过压力膜仪对土体进行脱湿试验，绘制出崩壁土体水分特征曲线，并进行曲线参数与影响因素的相关分析。结果表明：随崩壁土体垂直深度增加，崩岗土体塑性指数、黏粒含量、分形维数及磨圆度等均整体呈降低的趋势；水分特征曲线斜率随着深度的增加而增大，土壤持水能力减弱，残余含水率及VG模型参数a却随之减小，而参数n却随之增大；残余含水率、参数（a、n）均与容重和颗粒的磨圆度呈极显著相关；残余含水率可用容重和黏粒含量描述 ...

First, He Was Adam, and Then, She Was Eve
Sexuality, Gender &Policy, Volume 9, Issue 4, November 2026.ABSTRACT Trans* is an umbrella term that is used to describe people who identify with a gender that is different from their assigned sex at birth. There has been a marked increase in young people presenting to child and adolescent mental health services due to a lack of specialist gender clinics in the United Kingdom.
